Abstract: PURPOSE: To obtain high gradient magnetic-flux density and to enhance washing effect, by using cut pieces of wire rods as a filtering material in a magnetic filter for treating waste water, containing magnetic bodies.  
     CONSTITUTION: Filtering materials 4 consisting of cut pieces of wire rods are packed in a filtering tower 1 of an electromagnetic filter. Raw water such as waste water produced in steel industry is introduced from a liquid inlet and outlet port 7 and is filtered through a packed layer of the materials 4 by supplying electric current to an exiting coil 6, provided to the outside of the tower 1, to magnetize the mateial 4. Ferromagnetic SS and paramagnetic SS are captured satisfactorily with the aid of high magnetic-flux-density gradients produced by the concentration of magnetic flux at projected parts of the material 4, because the projected parts are formed by cutting the material 4. Treated water, after removing the SS components, is discharged from a liquid inlet and outlet port 8. Washing operation is performed by feeding reversed washing water to the port 8 to give the materials 4 fluid agitation in order to peel off the SS stuck to the material 4 and discharging the reversed washing water from the port 7.
